BOTTLE-nimma nnenlrnii I' v e -Appncationmea March 19,1928, seriarnaasasza f Y* The present inventionV relates tolbottle rinsing machines ofthe class designed more particularly vfor cleansing relatively small perfume bottles.

H5 The objects of the present invention in for conserving the cleaning fluidv necessary pressure for circulating vand spray# ing the cleaning fluid.

For Vfurther comprehension of the'invenv` i tion, and of the objects and advantages therei 20 of, reference is had to the following descrip-4 tion and accompanying drawings, land to the appended claims in which the vvarious features of the invention are more particularly pointedy out. n

Referring to the drawing in which similar characters of reference Vdesignate like parts throughout the several views:4 i

Figure 1 ot the drawings illustrates, my invention in `sectional elevation and Figure 2 is an enlarged detail view of a lilteringvdevice shown in connection with a pump plunger.

Numeral 5 of the drawing indicates a uid reservoir or tank having a bottom wall 6 and upwardly'andA inwardly flaring side walls 7 comprising the lower or body portion ot-the tank, and at the upper end thereof a hopper section 8 is formed provided with upwardly and outwardly flaring side walls 9.

Mounted within the tank .is a pump-easing 10, provided with a bottom flange 11 fixed to the bottom wall 6 of the tank. Inlet ports 12 extend through thewall of the casing adjacent thel lower end thereof, and above the ports an inwardly extendingrvalve seat 13 is formed within the casing, thevalve seatv being provided with a ball check-valve 14, and vdisposed above-the valve is a stop composed of cross wires 15 fixed in the walls of the casing.

` 50 At the upper end of the pump-casing 10, a

movement of the piston. f

A nozzle-head 22V 's 'detachably securedtoV cap or closure 16 is detachably secured theretov by screwthr eads, and LliXed to and extending above the cap are-apai'rof grip-pin`s 17 vbyv means of which thecap may be readily detached' or secured in positioni The capis provided with a central lperforation through which 'is slidably mounted aA4 tubular pump-` rod 18 having at'itsflowerend an exterior-ly threaded portionlada'pted to detaohablyv se` cure a piston coniprisinga p air'tof threaded Y washers*191havingvr an interposed relatively sott packing or piston member20 .closely-engaging 'the inner wallsof th'e pump casing.

Fixed to the rpiston-rod 18 aboveY the i piston is a sleeve" f 21 that `serves by itsa'engagement with the cap116`as a` stop to thefupward the uppery end ofthe` Vtubular piston-rod *18, and detachably secured to the nozzle-headare a lpair of spray nozzles' 23 having central passages"leadingvthrough crosspassages 2,4 Y

in the lhead i'fromthel central passage 25 of the pump-rod 1Q. Lateral spray passages are formedin the outer ends of the nozzlesf23, and grooves 26 arefformed in 'the'seatsot the' no'zzlefhead I surrounding the nozzles to provide escapehfor the cleaning luidf`discharged fromthe mouths of the bottles, the latter beingindicated'by` dotted lines 27. In its discharge vro'nn fthe "bottles ythe cleaning fluid', flowsfby gravity into the receiving hopper. v g j Y A main liltering device is provided for the bottom of hopper -consistingvot a perforated strainer plate' 28 fixed' tothe top 'ot thefcap, 16 of the pump-casing, andupon the strainer plate Aa' circular lterA fabri'cf29 lis' laid, the marginal edges 30 thereof` overlapping .the angular sidewalls 9ctthe'hopper,V Af'washe` erl isalso provided for the `1lt`er'arf1dcen!- tra'lly'overlays the-fabric, the severalparts' including the strainer platebeingfprovided with fperfo'rations to receive the tubular vpump'rrod 18 andthe gripepinsil'?, 4and byl means'ot thezlatter the capf16 may bereadily unscrewed from the pumpe-casing 10, andthe draws the liquid from the tank 5" through the ports l2 into the casing 10. For providing against solid impurities entering and Y choking up the spray nozzles due to accidental displacement of the main filtering device, the inlet ports 12 of the pump-casing are surrounded in spaced relation with an auxiliary suction filter 33 having perforated side walls exteriorly protected by a suitable filter fabric 34.

In the operation of the rinsing machine the attendant may use both hands and place a pair of bottles over the nozzles 23 and by exerting downward pressure rthrough the bottles against the nozzle-head 22 will depress the pump-rod 18 and piston 2O against the yielding resistance of the spring 32, the

downward movement of the piston closinO.

the check-valve 14 and forcing the 4liquid upwardly through the downwardly moving tubular pump-rod 18 and out through the spray nozzles 23 to theinteriorof the bottles, and then out through the mouths of the latter into the receiving hopper 8, the liquid portions passing through the cupshaped filtering fabric 29 while the solid impurities are retained by the filter.

The angular marginal portion 30 of the filter fabric overlapping the side walls of the hopper provides a close joint that permits only the liquid portions of the rinsing solution to pass into the tank 5 for recirculation and use. By thus sepa-rating the solid impurities considerable saving may be effected in the quantity of cleansing liquid consumed and which commonly consistswholly or in part of alcohol or similar volatile agents.

I claim:

1. In a bottle rinsing device, a Huid receiving tank having at its upper end a hopper provided with outwardly fiaring side walls, a pump casing fixed within said tank and having at its lower end a valve controlled inlet, a cap detachably secured at the upper end of said casing, a tubular pump rod sli'dable in said cap and having at its lower end a piston slidable in said pumpcasing, a nozzlehead at the upper end of said tubular r'od, and a filtering device detachably secured to said cap and removable therewith, the said filtering device having marginal edges engaging the flaring walls of said hopper.

2. In a bottle rinsing device including a tank provided with a receiving hopper, a circulating pump having a casing provided at its upper end with a detachable cap', and
